Table II
Individual variation in wave-length of neutral point compared to the expected influence of ocular pigmentation based upon 35 normal observers studied by Wright (reference 59).
Wave-length in mμ of the spectral region having the dichromatic chromaticity of a source of color temperature 5000°K
Illuminant D is produced by an incandescent lamp and Corning Daylite glass filter (reference 32, p. 60), and has a nearest color temperature (reference 28) of about 7500°K.
Illuminant S was found (reference 32, p. 58) by weighting Abbot’s “sun-outside-atmosphere” energy data by the inverse λ4 scattering relation, and has been designated as “limit blue sky.”
